"Guys relax, that was NOT me at A/V or in the @mrpink SUV. I'm taking this seriously and focused on the road ahead," Lohan wrote on her official Twitter page.

"I stayed in last night, after a pretty long day...and ordered sushi to my hotel. Don't believe every little thing you hear, unless you hear it from me. The support I have gotten has been great and means a lot."

It was reported that following Lohan's court hearing, she was spotted out at the A/V Club in Los Angeles on Monday night.

The Liz & Dick star is expected to spend 90 days in a locked rehab facility - time which includes the five-day jail sentence - after she entered a no contest plea to misdemeanour charges stemming from a 2012 car crash.

Lohan had until next Monday (March 25) to report to police, but the actress has turned herself in early.

The Los Angeles Times reports that she was booked and then released by Santa Monica police as a formality this afternoon (Tuesday, March 19).

In addition to rehab, Lohan must complete 30 days of community service and 18 months of psychotherapy. She must also pay several fines for violating her probation.
